welding methods of S420M steel

Plasma cutting has a wide range of applications. With different working gas, it can cut various kinds of metals that are difficulty to handle by oxygen cutting. Plasma cutting is fast and efficient when cutting metal with small thickness. The S420M steel cutting speed can reach more than 10m/min. Plasma cutting can get a clean, neat, non stick slag cutting surface, while the deformation and thermal effect of the incision are small, its hardness change is little, and the cutting quality is good.

ASTM A285 is an ordinary carbon steel used for fusion welding of pressure vessel equipment, such as S420M steel boilers, storage tanks, heat exchangers, etc. The tensile strength of the three steel grades (Grade A, Grade B, and Grade C) ranges from 310-515Mpa, and ASTM A285 steel plates are usually delivered in the rolled state. According to user requirements, S420M steel is produced by processes such as compaction, semi-compaction, edge sealing and boiling water.

Every customer who has visit us and witness the steel materials before delievry will be impressed by our quality control departemnt. Even not come to inspect the steel materials before delievry, our quality control departemnt will also send inspection report to the customer. For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.

The company always adheres to the concept of green production, follows the development path of innovation, transformation and improvement, and has carried out in-depth cooperation with Zhengzhou University and other scientific research institutes, planning from a high starting point, strict standard design, and successfully implementing engineering projects With nearly 20 research and development projects, the company's production technology and equipment are at the forefront of the industry, and indicators such as environmental protection, energy consumption, cost, and resource utilization have reached the advanced level in the industry.

Our products have perfect after-sales system to protect the interests of customers. At the same time, we can according to S420M steel customer's requirements, processing requirements, cutting technical requirements, etc., to develop detailed solutions for customers, so as to make customers 100% satisfied. If you have any requirements and needs, please contact us in time.
